The Effective Control of Porcine Immunosuppressive Diseases by Fermentation Bed

Abstract: Since 2005, the farms have suffered from viruses, such as blue ear, porcine circo virus, and swine fever, and have suffered heavy losses. The national authorities have carried out a great deal of prevention and control work, and the epidemic has been stabilized, but the follow-up impact has been achieved. The hugeness has brought great inconvenience to the rearing of pigs and immune prevention and treatment. This article focuses on the analysis of the hazards and causes of the immunosuppression diseases of pigs, and combines the "breeding bed" with this new breeding mode to give feasible operations. Suggest.
First, immunosuppression disease is huge!
Immunosuppressive disease is a type of disease that can cause immune suppression in the body. The more common immunosuppressive diseases include: Porcine blue ear disease, porcine circovirus disease, and swine fever. These diseases have brought unprecedented opportunities to the pig industry. Disasters, such as blue-ear disease, which mainly causes reproductive problems such as preterm birth, miscarriage, stillbirth, and mummification of pregnant sows, and respiratory diseases of young pigs, can cause immunosuppression of the body and reduce the body's immune system. Therefore, it is often associated with other viruses. Disease and bacterial diseases mixed infection; another example is the outbreak of pigs in summer 2006, "unnamed fever" is caused by the mutation of the blue-ear virus, followed by other viral diseases and bacterial diseases caused by pig fever and acute death, for the pigs The field caused huge losses.
Second, the root of the study, the detailed study of the reasons for the occurrence of immunosuppression disease shows that the factors causing pigs suffering from immunosuppression mainly include the following aspects:
First, feed nutrition factors. Modern feeding standards are biased towards the growth rate of pigs, pursuing high feed remuneration and lowering the feed coefficient. As a result, the lack or imbalance of vitamins, amino acids, and certain trace elements in the feed will reduce the body's immune response. For example, deficiency of vitamin A can lead to atrophy of lymphocytes, affect lymphocyte differentiation, proliferation, receptor activation and expression ability. As a result, the number of T lymphocytes in the body decreases, the phagocytic capacity of phagocytes decreases, and the ability of B lymphocytes to produce antibodies decreases. This is one of the important reasons why pigs are susceptible to immunosuppression.
Second, the vaccine and immunization program factors. Some aquaculture plants do not pay enough attention to vaccine immunization and lack the basic knowledge of vaccine use and maintenance, leading to vaccine failure and reduced or lost immune effects. Some farms do not have strict and reasonable immunization procedures, neglecting the effects of maternal antibodies and immunization intervals.
Third, drug and disease effects. Glucocorticoid drugs not only have anti-inflammatory, anti-toxic and anti-shock effects, but also have anti-immune effects. Such drugs will reduce the immune function of animals and cause secondary infections in animals.
Fourth, feeding management and breeding mode, environment. Traditionally, large-scale farming of cement, pigs seldom move, polluted air in the pens, poor feeding environment lead to low immunity of pigs; when pigs are encountered in transit, refueling, introduction and transportation, etc. Injury, these stresses can stimulate the pituitary gland to produce adrenocorticotropic hormone, which stimulates adrenocorticotropic hormone, and adrenal cortical hormone can damage T lymphocytes, inhibit macrophages, and increase the catabolism of immunoglobulins. , thereby affecting the immune response.
Third, prevention and control of immunosuppression diseases, focusing on breeding mode!
Routine measures to prevent and treat immunosuppression include: 1. Strictly control hygiene and disinfection; 2. Strengthen isolation and strictly control the introduction of customs; 3. Strictly select vaccines and formulate reasonable immunization procedures; 4. Early detection and early treatment. However, these measures are cumbersome, and it is difficult to strictly implement them. The author here recommends a new method for everyone, that is, adopting a new breeding mode “Goldbaby Fermenting Bed Pig Raising Law” to control immunosuppression diseases.
Why use pigs in a fermentation bed to effectively control immunosuppression? This requires us to understand the characteristics of the virus and the fermentation bed that cause immunosuppression. In the case of the typical immunosuppressive PRRS, the culprit of PRRS is the blue ear virus, which is inactivated at room temperature and below 37°C and completely inactivated at 56°C for 45 minutes. And chemical resistance is weak and sensitive to ether and chloroform.
For the blue-eared virus, it can completely adopt the fermentation bed breeding mode to eliminate the blue ear virus. Take the DNA fermentation bed as an example. In the 50-cm litter layer, beneficial functional microorganisms are both quantitatively and functionally. All of them have absolute and overwhelming advantages. The valuable function microorganisms of Kumba decomposes the feces into the bacterial proteins and trace elements while also releasing a large amount of heat. Therefore, the temperature of the central fermentation layer is basically maintained at 40-60 degrees. Fermentation or fermentation intensity is very small, and it is maintained at twenty degrees for many years. This temperature and flora structure do not have the survival and propagation opportunities of the blue-ear virus at all. The author often serves as the technical service personnel of Beijing Huaxia Kangyuan Company. The big pig farms did a service and found that anyone who used the Jinbao fermentation bed to raise pigs had never encountered blue ear disease, which directly proved the above point of view.
In addition, pigs raised in a tutoring bed can be fermented and decomposed into bacterial proteins and trace elements under the action of microorganisms, so they can supplement the nutrients needed for growth and reproduction of pigs in a balanced manner and raise the antibody level of pigs; at the same time, pigs rarely get sick. Basically no drugs, no anti-immune phenomenon will occur. The fermentation bed mode of raising pigs, paying attention to the ventilation settings of the pig house, and the natural purification of microorganisms, can greatly change the environment of the pens, make the dirty smell away from the pig house, and enhance the immunity of the pigs. From the above analysis, it can be found that the pigs in the fermentation bed can effectively eliminate the factors of the pigs suffering from immunosuppressive diseases and prevent the pigs from being infested by immunosuppressive diseases.
After adopting a safe and reasonable breeding mode, it should be said that the possibility of blue-ear virus, porcine circovirus, swine fever virus, etc. hitting pig farms is already very low. If the first four measures are combined, then immunosuppression such as blue ear disease should be adopted. The disease basically missed the farm.
